Summary:There is a concern over large, fluctuating wind power injected into a power system, which could affect stability, frequency and power quality of the power system. A method of using three-terminal HVDC system to bundle large scale wind farms with conventional power plants is proposed to overcome this problem. The wind power fluctuation is canceled by regulating the power from the conventional power plants. Topology of the scheme is described. A control strategy particularly suitable to cope with wind power fluctuation is designed. Novel fault ride through mechanisms are designed to enable safe operation of the system. Simulations using PSCAD/EMTDC verify the successful operation of the system during starting-up, steady state, wind power variations and faults. The proposed scheme provides a novel way to deal with the integration of large scale wind power.
